FLUE-STPPEF?.

SPECIFICATION forming .part of Letters Patent No. 391,870, dated Uctober 30, 1888.

Application filed Marcil 52'2, 1858. Serial No. 268,150. (No model.)

.it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a plan View from above, showing the stopper-disk in section. Fig. 2 is a side view showing the stopper-disk partly in section.

A is the stopper-disk which closes the hole inthe wall after the stove-pipe has been taken down. This stopper-disk is made of plasterof-paris or any other similar material which is appropriate for the purpose.

B is a plate, one end of which is turned down, forming the ilange b. The plate is split upon each side of this ilange and bent in opposite directions, forming the tangs G, which are embedded in the said plaster disk. The other end of plate B is also bent down, and has its extreme end bent again parallel with the plate, thus forming the vertical flange D and the horizontal fiange E.

F is an eyebolt riveted into the flange E, and having` the arms G pivoted upon its stemf between the eye and the said flange.

H is a screw which passes through the eyebolt F, and is journaled in the holes d, formed through the vertical flanges b and D of the plate B. A knob, l, is secured .upon the end of the screw H, outside the stopper-disk, for rotating the screw and working the retainingarms G.

J is a plate provided with the vertical liange j, havinga screw-threaded hole, j, with which the screw H may engage.

K are links which are pivotally connected to the end of plate J and to the arms G by the pins k.

The stopper is applied to the hole in the wall when the arms G are near together and can pass through the hole, and the screw is then. revolved by means of the knob. rlhe revolution of the screw draws upon the plate J, which forces the arms G- apart by means ofthe links K until the said arms hold the stopper-disk securely fastened in the hole, as shown in Fig. l of' the drawings. i The revolution of the screw in the opposite direction will draw the retailiin g-arms together and release the stopper-disk.

It will be seen that this device is extremely simple and eliicient, and that it is very cheaply made on account of having so few parts, and those being of a very simple nature.

What I elaimis- 1. The combination, with a stopper-disk, of a plate embedded in the disk and provided with vertical fianges at each end, a screw journaled in the said vertical flanges and provided with a knob for rotating it, the retaining-arms pivoted at one end to the said plate, a sliding plate provided with a vertical flange having a screw-threaded hole engaging with the said screw, and the links pivotally connecting the said arms and sliding plate, substantially as set forth. v

2. The combination, with a stopper-disk, of a plate secured in the disk and provided with vertical flanges, a screw journaled in the said vertical flanges and provided with a knob for rotating it, the retaining-arms pivoted to the said plate, and a sliding plate engaging with the said screw and operatively connected with the retaining-arms, substantially as set forth.

8. The combination, with a stopper-disk, ot' a plate provided with tangs securing it in the disk, the vertical flanges at each end, and the horizontal fiange E, a screw provided with a knob at one end and journaled in the said vertical flanges, the retaining-arms pivoted at one end to the said horizontal flange, a sliding plate provided with a screw-threaded hole engaging with the said screw, and the links pivoted to the retainingarms and to the said sliding plate, substantially as set forth.

4. The combination, with a plaster flue-stopper disk, of a plate provided with tangs embedded in the disk, the vertical flanges at each end, and the horizontal flange llt, an eyebolt riveted in the said horizontal flange, the reto the retainingarms, substantially as Set taining-arms pivoted upon the stern of the said forth. Io eyebolt, the screw provided with a knob at In testimony whereoflaffixmy signaturein one end, journaled in the said vertical anges presence of two Witnesses.

and passing through the eye of the eyebolt, VILLIAM PENN VALTER. the sliding plate provided with a screw-I Witnesses:

threaded hole engaging with the said screw, S. J. BENTLEY,

and the links pivoted to the sliding plate and L. R. YEAGER.
